Brighton
At a glance
Be At One Brighton is a cocktail-led bar at 5 Castle Square, offering a lively setting for drinks, light food and late-night celebrations. The venue combines a colourful, playful approach to cocktails with a stylish bar environment, making it suitable for casual meetups, dates, after-work drinks and group occasions.
Cocktails are the main focus, with a broad drinks menu that includes familiar favourites such as Margaritas and Espresso Martinis, sparkling serves, and alcohol-free mocktails. Fresh beer is also available on tap, while bar bites provide a simple food option alongside drinks. The overall offer is designed around social drinking rather than a full restaurant meal.
The atmosphere changes with the time of day. Earlier visits suit afternoon catchups and relaxed drinks, while the bar becomes a later-night destination for celebrations and dancing. Music, cocktails and a sociable setting give the venue an energetic character, with the bar team central to the experience.
Regular promotional activity forms part of the venue’s appeal. Happy Hour runs daily, alongside themed cocktail offers and student and hospitality industry deals. These promotions are subject to change, so current terms are best checked before a visit. Cocktail masterclasses and drinks packages are also available for selected occasions, adding an organised activity for birthdays, hen and stag parties, and other group gatherings.
Be At One suits visitors looking for a dedicated cocktail bar rather than a quiet dining room. It works for informal drinks, celebrations and evenings that continue late, with bar bites available for sharing or a quick accompaniment. The drinks-led format also makes it a practical choice for groups planning a social occasion in Brighton.
The venue has a smoking area and Wi-Fi, and its facilities include a cocktail menu, a Christmas bar and options for private or organised celebrations. Reservations are available, which can help groups plan ahead for busy periods. The venue’s cocktail-focused style, late-night atmosphere and varied drinks selection define its character at this Castle Square address.
